The age of Udachnaya-East kimberlite: U/Pb and Ar/Ar data.

The article discusses the study done to examine the age of Udachnaya-East Kimberlite by using Uranium-lead (U/Pb) dating of perovskites and zircons and Arsenic dating of xenoliths and xenocrysts. Topics discussed include difficulty in the determination of the age through isotopic methods, low Uranium content in the mantle zircons, and using isochrone method for the estimation of the kimberlite age.
